METHOD FOR PRODUCING LINEN YARD BY DRY SPINNING Russian patent published in 1997 - IPC

FIELD: textile industry. SUBSTANCE: method involves emulsifying filament; forming fibrous ribbon and providing softening of ribbon; providing preliminary thinning and leveling of ribbon on ribbon processing machine; forming bobbin for spinning machine; effectuating final thinning of ribbon dispensed from bobbin and twisting of fibers with following winding of yarn. Upon preliminary thinning and leveling of ribbon prior to final thinning of ribbon on spinning machine, ribbon is additionally wetted to humidity of 20-30%. Prior to delivering bobbin to spinning machine, bobbin is softened for 12-36 hours. Additional softening is effectuated prior to bobbin formation or during softening. Wetting may be conducted by spraying finely dispersed liquid onto ribbon, saturating ribbon with liquid or blowing liquid-air mixture through bobbin. Additional wetting and softening of ribbon conducted prior to spinning facilitate disintegration of fibers so that yarn is formed from less coarse filament complex. EFFECT: increased number of filaments in yarn section and improved strength. 7 cl, 4 dwg
